Foods to Absolutely Avoid if You Suspect Gluten Sensitivity or Celiac Disease

27. Lipsticks, Lip Balms & Toothpaste: Trace but Troublesome

You may not eat them—but if it goes on your lips or into your mouth, it deserves scrutiny. Some lipsticks, balms, and even toothpaste formulations include gluten-derived ingredients such as hydrolyzed wheat protein or wheat germ oil. Though the quantities are small, for those with celiac disease or strong gluten intolerance, even trace ingestion—especially multiple times daily—can cause inflammation or symptoms. Look for gluten-free certified personal care products and oral hygiene items to stay completely protected, even in your beauty and self-care routines.

28. Blue Cheese & Mold-Ripened Cheeses: A Fermented Surprise

While most cheeses are naturally gluten-free, certain mold-ripened varieties—like traditional blue cheese—can be cultured using bread-derived mold spores. Though this practice is declining, it still exists in artisanal or imported batches. While many people with gluten sensitivity can tolerate blue cheese without issue, celiac patients should double-check the source of the mold. Safer alternatives include certified gluten-free blue cheese or opting for other aged cheeses like cheddar or gouda, which carry less fermentation risk and zero wheat exposure.
